(CNN) -- The tennis year's most glamorous tournament is underway in the chic setting of Paris as the world's leading players battle to claim the second gland slam title of the season.

The French Open at the iconic Roland Garros stadium is a competition rich in history and drama, and 2010 is set to be no different.

Roger Federer is aiming to retain the title he won in 2009, a victory that gave him a much-coveted career grand slam, while his main rival Rafael Nadal will be looking to reassert his dominance on clay after lifting the trophy four times in a row between 2005 and 2008.

In the women's singles Svetlana Kuznetsova is the defending champion but faces stiff competition in the face of the Williams sisters, as well as four-time French Open champion Justine Henin, who is competing for the first time since coming out of retirement.

Since the French Open became the first major tournament to allow professionals to compete in 1968, there have been many memorable moments, and here CNN World Sport lists our top 10.

Who could forget the tears of Andre Agassi and Roger Federer after they finally secured the French crown and completed a career grand slam in 1999 and 2009 respectively?

Or the epic women's singles final in 1986 when Chris Evert won a record seventh title, beating her old foe Martina Navratilova. Then there was Monica Seles claiming the French Open for the first time in 1990 at the age of just sixteen.
